Detailed Description

Basic sub-grid obstacle drag model. Details supplied by J Puttock 2/7/06.

Sub-grid drag term

The resistance term (force per unit of volume) is given by:

$R = -\frac{1}{2} \rho \vert \dwea{\vec{U}} \vert \dwea{\vec{U}}.D$

where:

$ D $ is the tensor field "CR" in $m^{-1}$

This is term is treated implicitly in UEqn.H

Sub-grid turbulence generation

The turbulence source term $G_{R}$ occurring in the $\kappa-\epsilon$ equations for the generation of turbulence due to interaction with unresolved obstacles :

$G_{R} = C_{s}\beta_{\nu} \mu_{eff} A_{w}^{2}(\dwea{\vec{U}}-\dwea{\vec{U}_{s}})^2 + \frac{1}{2} \rho \vert \dwea{\vec{U}} \vert \dwea{\vec{U}}.T.\dwea{\vec{U}}$

where:

$C_{s}$ = 1

$\beta_{\nu}$ is the volume porosity (file "betav").

$\mu_{eff}$ is the effective viscosity.

$A_{w}^{2}$ is the obstacle surface area per unit of volume (file "Aw").

$\dwea{\vec{U}_{s}}$ is the slip velocity and is considered $\frac{1}{2}. \dwea{\vec{U}}$ .

$ T $ is a tensor in the file CT.

The term $G_{R}$ is treated explicitly in the $\kappa-\epsilon$ Eqs in the PDRkEpsilon.C file.
